US Secretary of State Marco Rubio has submitted a draft proposal for monitoring a ceasefire in Ukraine to Ukrainian and European Union officials. The proposal was presented during a series of meetings hosted by French President Emmanuel Macron to push for European involvement in a ceasefire. The US is open to attending talks if there are advancements in negotiations, which have been stalling for weeks. Russian representatives refuse to take any deal that does not address the root causes of the conflict. US officials have pushed several concessions, including the possibility of Crimea becoming part of Moscow's territory.
